Best Action Series on Prime Video (2026)

There's a reason Reacher is the show people recommend to everyone they know. All three seasons are streaming now on Prime Video and the numbers speak for themselves. Season 3 pulled in 54.6 million viewers globally in its first 19 days, making it the most-watched season on Prime Video since Fallout Season 1 over the same timeframe.

Every season has grown its audience, with Season 3 marking a 0.5% increase over Season 2. More than half of viewers came from outside the United States, with particularly strong performance in the UK, Germany, and Brazil. Alan Ritchson owns this role completely. The show holds an 8.0 on IMDb from nearly 300,000 ratings, Season 1 sits at 92% Certified Fresh on Rotten Tomatoes, and it's already been renewed through Season 5.

Fans love it because it delivers exactly what it promises. No padding, just a brilliantly physical protagonist solving problems in the most satisfying way possible. If you haven't started yet, you have three seasons of pure adrenaline waiting. If you have, you already know why it keeps climbing back into the Top 10 months after each season drops.

Jack Ryan was the series that proved Prime Video could go toe-to-toe with anyone in the action space. Across four seasons, John Krasinski transformed Tom Clancy's CIA analyst into one of the most compelling characters in modern espionage television.

Season 2 drew 7.3 million viewers to its premiere episode within seven days, the largest figure for any Amazon show at the time. Season 3 hit number one on Nielsen's streaming originals chart. The series holds an 8.0 on IMDb from over 190,000 ratings, and its influence is still being felt. The franchise expanded into the film Jack Ryan: Ghost War, which topped Prime Video's global film chart in May 2026 and accumulated over 809 million minutes watched.

All four seasons remain available on Prime Video, and they reward rewatching. The geopolitics feel real, the set pieces are cinematic, and Krasinski brings a grounded intensity that makes you believe every second of it.

The Terminal List arrived in July 2022 and immediately made history. In its debut week, the series accumulated 1.6 billion minutes viewed, placing it among the biggest streaming launches of that year. Chris Pratt delivers something completely different here, stripped of charm and humour, playing a Navy SEAL hunting down the people who destroyed his platoon.

The audience score on Rotten Tomatoes sits at 92%, and despite being four years old with no new season yet, the show still regularly appears in Prime Video's global Top 10 in multiple countries. It spawned a spin-off, The Terminal List: Dark Wolf, which became the second most-watched show globally on Prime Video on its launch day.

Season 2 arrives on 21st October 2026, which makes right now the perfect time to watch or rewatch the original. Eight episodes, uncompromising pacing, and a lead performance that will keep you locked in until the credits roll on the finale.

The Boys didn't just succeed. It became one of the defining shows of its era. Five seasons, 57 million viewers per episode for its final run, and the kind of cultural impact that spawned an entire franchise. Season 5 ranks among the 10 most-watched seasons of any Prime Video original series ever, and generated the largest three-week ratings surge of any show or film on the platform to date.

The premise is simple but electric. What happens when superheroes are corrupt, corporate-owned, and accountable to no one? Karl Urban, Jack Quaid, and Antony Starr deliver performances that have kept audiences hooked since 2019. The show holds an 8.5 on IMDb, and all five seasons are available to stream now. Whether you're watching for the razor-sharp satire or the jaw-dropping action sequences, this is the show that redefined what superhero television could be.

Set in the same universe as The Boys, Gen V takes the action to America's only college for superheroes, where gifted students compete for the top ranking and a shot at joining Vought International's elite team. It's a different energy entirely, younger, faster, and packed with moral dilemmas that hit just as hard as the fight sequences.

The series holds a 94% on Rotten Tomatoes and a 7.6 on IMDb, and its Season 2 premiere scored the show's biggest streaming audience to date, landing in the top 8 most-watched streaming originals alongside major titles from Netflix and Hulu. Jaz Sinclair and Patrick Schwarzenegger lead a cast that brings real emotional weight to a world where superpowers come with devastating consequences.

Both seasons are streaming now on Prime Video. If you loved The Boys and want more from that universe, this is where to go next.
